DOMENICO DI LEONARDO, OF ELLWOD/CITY, PENNSYLVANI.

ENGINE-STARTING DEVICE.

To all whom it may concern: y

Be it known that l, DOMENICO `Di LEON- Anno, a citizen of the United States, residing at Ellwood City, in; the county of Lawrence and State of Pennsylvania, have invented new and useful Improvements in Engine- Starting Devices, of which the following is 4 groove.

Another object of the invention, andin connection with said mentioned object., f is' to provide means which may be thrown into or out of operative relation with the Ygroove referred to.

Another object of the invention in connec-v tion with said mentioned objects', is to provide means whereby a movable'device may be operated after the projection of the means into the'groove referred to, so as to cause rotation or'turning over of the engine Shaft. n

A. further object of the invention is to generally improve the construction of a starter of this type.

Further objects of the invention, mostly minor in nature, will appear fromthe description following taken in connection with the drawings accompanying this application, wherein the preferred embodiment is shown. n

In said drawings z-Figure 1 is a side view but with the guide rails mostly broken away; Fig. 2 is a plan view; Fig, 3 isan end view; Fig. 4 is a view partly in elevation and partly in section, illustrating the pin means for engaging the spiral groove of the rod or the extension of the engine shaft; Fig. 5 is 'a detail view illustrating the rod or extension of the main shaft showing one of the pins in the groove thereof, and; Fig. 6 is a detail view illustrating part of the pin operating means.

Like reference characters designate like parts throughout the several viewsof the drawings.

Referring specifically to the drawings, 1 designates suitable guide rails provided -with grooves 2 in which are mounted wings specification of Letters Patent. Patented De@ 15, 19ML Application filed September 27,1912. Serial No. 722,610.

body 4 has secured thereto upper and lower frames 5 which are secured in yplace by means of bolts 6 passing through lugs 7 thereof and through the wings 3.

Numeral 8 designates the main shaft of an internal combustion engine, and 9 designates an extension shaft which is fastened to rotate with the shaft S, and which` may be formed integralor of the same piece therewith, if desired. The shaft 9 extends l loosely through a central opening in the body4. Said shaft 9 as shown, is provided with a. spiral groove 10 which in effect, converts the shaft into a screw'rod. l K Suitably mounted in cross arms 11 of the frames 5, are shafts 12, which shafts at their inner ends are provided with lscrew threads at 13 and extend into openings '.14 of the body 4 so that the threadswill engage screw threads provided in said openings. On each shaft'12 is provided a pinion or gear wheel 15. In the'cross arms 11 are also slidably and. at one end is provided with screw4 threads engaged by a nut 21. rAt its other end the 'rod 2O is provided with' a stop arm designated 22. slide a 'cross head 23 which is provided with an opening through which said yrod 20 ex-' tends. 'At each end of the cross head 23 is pivoted as at 24, pitmen`25 whichin turn are pivoted at 26 to crank arms 27 rigidly fastenedonthe shafts 16.` To the cross head 23 is pivoted at 28 a yoke 29, intoy an elongated slot 30 of which,provided by the arms ofthe yoke, extends and moves the stop arm 22. y To the body 4 is fastened a main actuating rod 31, which may have a reduced shank 32 passing through the body and beyond which body it is provided with screw threads adapted to be engaged by a nut 33. To the rod 31 lat 34, is pivoted a link 35 which link 35 in turn, is pivoted at 36 to a main operating lever 37. Said lever 37 is pivoted at 3Sto a suitable part such as 39 which may be a portion of the frame ar chassis of an automobile or self-propelled vehicle, n If dei' rod which is so On the rod 20 is adapted to ioo sired, any suitable means may be employed to lock or secure the lever 37 against acci-y dental movement.

To the lever 37 are secured brackets 40 in which is turnably mounted a rod 41 having a crank arm 42, to which is pivoted at 43 a link 44. Said link 44 is pivoted at 45 to a connecting rod 46 secured or connected in any suitable manner to the yoke 29. On the lever 87 is fastened a toothed segmental rack 47 adapted to be engaged by suitable meansV located adjacent a hand-engaging member 48 on the rod 41 for the purpose of fastening or locking the rod in suoli position as to prevent accidental movement thereof. Such means engaging the rack may be a tooth such as 49, preferably made of spring metal and fastened to the rod 41 or hand member 48.

In operation, in order to turn or rotate the engine shaft in order to start the engine, the rod 41 by means of manual engagement with the member 48, is turned so as to turn the shafts 16 and accordingly the gear wheels 19 through the medium of the crank arm 42, link 4&1, rod 46, yoke 29, pitmen 25 and crank arms 27. Upon the shafts 16 and gear wheels 19 being rotated, the threads 17 engage the appropriate threads ofthe body 4 in the opening 18, which causes the shafts to move the gears laterally with respect to the body. r1`he gears 19 in turning, turn the gears 15 which in turn rotate the shafts 12 and cause the saine to slide or move laterally with respect to the body and to the same extent as do the shafts 16. By thus sliding or moving the shafts 12 the same may be brought into suoli position that the inner ends thereof will enter or engage the spiral groove 10 of the extension sliaftf9. The direction of the screw threads of the several shafts 12 and 16 are of course, such as to enable the movement described to be had. After the shafts 12 have been thrown or moved into the groove 10, the operating lever 37 is moved so that the body 4 will slide along the shaft 10, being guided in the rails 1 by means of the wings 3. During such sliding movement of thev body 4, the shafts 12 will act against the walls of the extension shaft 9 at the spiral groove, and by the engagement therewith will cause the shaft 9 to turn or rotate, and accordingly the shaft 8 to turn or rotate and thereby start the engine. After the engine has been started as described, the rod 41 may be returned or moved to such position as to cause the several parts described to operate, to remove the shafts 12 from projection into or engagement with the groove 10.

It may be stated that the device is of such form that the same may be located on either end of the engine shaft desired, and that the same forms an attachment which may be suitably connected up or fastened to the main shaft of an engine without necessitating alteration of any parts thereof.

As only the preferred embodiment of my invention has been illustrated and described, it is to be understood that changes therein may be made provided the same fall within the spirit and scope of the appended claims.
